1. A method for analyzing a sample, the method comprising:
introducing a precursor ion of a sample into a mass spectrometer comprising a single ion trap; and
analyzing the sample via the mass spectrometer that applies a plurality of scan functions to the single ion trap to fragment the precursor ion and simultaneously eject a product ion of the precursor ion in a manner that preserves in time a relationship of the precursor ion and the product ion.
